The Sun SPARC Enterprise T5440 Server is the Most Powerful Four-Processor System in Compute-Intensive Throughput Tests

(As of Monday, 13 October 2008)

Oracle's Sun SPARC Enterprise T5440 server is the first chip multithreading (CMT) technology server that scales to address traditional midrange applications. Four UltraSPARC T2 Plus processors at 1.4GHz combined with the advanced features of Oracle Solaris and Oracle Solaris Studio 12 enabled the server to deliver unprecedented levels of compute performance with world record-setting four processor integer and floating point throughput scores.

The SPEC CPU2006 benchmark provides a broad variety of workloads and better real-world applicability of the results than the previous versions of this benchmark. It consists of two benchmark suites — one suite measures and compares compute-intensive integer performance and the other measures and compares floating point performance. The benchmark exercises a computer's processor, memory architecture and compilers on a variety of compute intensive workloads, including protein sequencing, MPEG-4 decoding, XML processing, fluid dynamics, structural mechanics, and speech recognition. 

Competitive Comparisons Table (best four-processor systems results)

• Surpassing competing quad-processor systems from HP and IBM, the Sun SPARC Enterprise T5440 server equipped with four 1.4GHz UltraSPARC T2 Plus processors posted four processor world records on both the integer and floating-point throughput suites of the SPEC CPU2006 benchmark.
• On the integer-intensive throughput tests, the Sun SPARC Enterprise T5440 server delivered 24% higher performance than the quad-processor POWER6-based IBM System p 570 server, and up to 2.4x more performance than the HP Integrity rx6600 server with four Itanium2 processors.
• On the floating point-intensive throughput tests, the Sun SPARC Enterprise T5440 server delivered 47% higher performance than the quad-processor HP DL 580 G5 server equipped with the latest six-core Intel Xeon CPUs. The server also outran the HP Integrity rx6600 server with four Itanium2 processors by 2.4x.
• In addition, the Sun SPARC Enterprise T5440 server delivered a four-processor world record score of 212 on the SPECfp_rate_base2006 suite of the benchmark. The "base" scores are produced using less optimized benchmark binaries compiled under stricter guidelines. Although "base" scores may not reflect the ultimate performance of the system, some end users, who may prefer to spend less time tuning their compiler optimizations, may find them more relevant.
• The Sun SPARC Enterprise T5440 server, powered by four UltraSPARC T2 Plus processors, delivers 1.9x of the integer and the floating point throughput performance of the Sun SPARC Enterprise T5240 server, the dual-socket system powered by the same CMT processors. The Sun SPARC Enterprise T5440 server demonstrates that an elegant CMT design can scale well for SMP applications and provides unprecedented computing capacity for this segment of the market.
• These results demonstrate that the UltraSPARC T2 Plus chip — the third generation of CMT processors — continues to show its ability to scale and process highly compute-intensive workloads.
